The IMTANH function returns the hyperbolic tangent of the given complex number. For example, a given complex number "x+yi" returns "tanh(x+yi)."
Parts of an IMTANH function
IMTANH(number)
| Part | Description | Notes |
number |
The complex number for which you want the hyperbolic tangent. | This can be either the result of the COMPLEX function, a real number interpreted as a complex number with imaginary parts equal to 0, or a string in the format “x+yi” where x and y are numeric. |
Sample formulas
IMTANH(COMPLEX(4,6))
IMTANH(4)
IMTANH("2+3i")
Notes
The IMTANH function returns an error if the given number isn't a valid complex number.
